SHEET-METAL CAN.

SPECIFICATION forming part of Letters Patent No. 267,013, dated November7', 1882,

Application filed September 30, 1882. (No model.)

I 0 all whom it may concern Be it known that I, EDWIN NORTON, a citizenof the United States, residing in Chicago, in the county of Cool: andState of Illinois,

have invented a new and useful Improvement in Sheet-Metal Cans, ofwhichthe following is a specification.

My present invention relates more particularly to improvements inpaint-cans. This class of cans are usually provided with two covers, oneinner cover of thin metal or taggefls tin, which is united to the can bya close seam, so as to make, the can tight, and which may be readilycutout when the can is to be opened, and an outer slip-cover, whichserves to protect the inner thin cover while the can is beingtransported and also serves to close the can from time to time as thecontents are used after the thin inner cover has been cut away; and myinvention consists in providing the can-body with an inturned flangeover which is crimped or folded the inner edge of a seamless ring, theouter edge of the same being folded or crimped over the depending flangeof an ordinary slip-cover, so as to form a tight joint when the cover iscrimped on in this way, and at the same time admit of the crimped outeredge of the seamless ring being pressed out or off and the cover removedwithout injury. By this means it will be observed that one and the samecover may be used to close the can tight, and also as an ordinaryslip-cover after the can has once been opened, and that the inner thincover may, if desired, be dispensed with, as the can may be as readilyopened by simply pressing off the overlapping crimp or flange of theseamless ring or flange as by cutting out the inner cover, if one shouldbe used.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is-a central section of my improved can,

showin g the form of the same when two covers are used. Fig. 2 is asimilar view showing the same when but a single cover is employed,

and Fig. 3 is a section showing the form of the seamless ring beforebeing crimped over the cover.

In the drawings, A represents the can-body, which is provided with aninturned flange, (t.

B (shown in black in the drawings) is a seamless ring, soldered to thetop of the can-body, and having its inner edge, I), folded or crimpedover the flange a, which materially serves to strengthen the top of thecan. The outer part of the seamless ring is crimped so as to form anannular groove or recess, in which fits the depending flange c of thecover 0, and when the can is closed the outer edge, b, of the seamlessring is crimped over the flange 0, thus forming a tight joint with thecover without the use of solder. When the can is to be opened the flangeor shoulder b is simply pressed out or 01f by running any ordinary knifeor tool around the top of the can, and then the cover may be removedwithout injury thereto, so that it afterward may be used as any ordinaryslip-cover to close the can.

In Fig. l I have shown the can-body provided with a shoulder, d, nearits top, so that an outer slip-cover, D, may be applied outside thecover O and seamless ring B, and in that case the inner cover, 0, wouldof course be made of thin metal; but I consider the form shown in Fig. 2as the preferable mode of practicing my invention.

I claim- The combination of the can-body provided with an interiorflange with a seamless ring, having its inner edge folded or crimpedover said flange on the can-body, and a slip-cover
